WALL FomR SHIPS.

SPECIFICATION forming part of Letters Patent No. 431,329, dated July 1, 1890.

Application filed April 11, 1889. Serial No. 306,855. (No model.)

To all whom it Irl/ay concern.-

Be it known that I, CARL WILHELM MARTIN FRIEDRICH BsING, a subject of the Grand Duke of Oldenburg, residing at Oldenburg, in the Grand Duchy of Oldenburg, German Empire, have invented neuT and useful Improvements in falls for Ships, of which the following is a specification.

This invention relates to ships walls; and has for its object to provide ships walls With a lining whereby water Will be prevented from entering within the hull of the ship through a hole or other defective part in the wall of a vessel made by a projectile or other means.

To this end the walls of a ship forming the hull and the partitions forming the so-called water-tight compartments of a ship, and termed the coffer-dams, are provided with a suitable Water-absorbent material, preferably consisting of sponge.

In the accompanying drawing is shown a portion of the wall of a ship provided with an absorbent lining in accordance with this invention. A

l indicates the skin of a ship, and 2 the lining or inside planking secured to the ribs. NVithin the ships walls so constructed is placed and packed in any suitable manner a lining of absorbent material 3, preferably of sponge. In the same way the walls forming the partitions or coifer-dams of the watertight compartments may be provided with a water-absorbing lining.

Sponges either in aloose state or compressed into balls, which may be connected together by any suitable adhesive substance, are pressed into the walls of the ship. The sponge may be pressed into the walls in the proportion of from one hundred and sixty to one hundred and eighty kilograms to every cubic meter of space. This packing will be facilitated by employing the compressed balls above mentioned. Ordinary sponges, (seasp0nge,) such as usually used for washing and bathing` purposes, are employed, and large and small and waste Sponges are t for the purpose.

The sponge pressed into the Walls of ships, as above described, prevents water from penetrating into the hull through a leak, holes, or other defect in the hull, and thereby keeps up the hull of the ship.

The sponge acts automatically in first completely fothering the leak, as owing to the elasticity of the sponge the hole or other opening formed in the hull is closed immediately after it is made by the action of the water on the sponge, causing it to swell, and as the Water penetrates more and more into the sponge t-he latter acts as a filter, smallquantities of water trickling through without carrying away any of the sponge, until the sponge is Inoistened and iilled, the moistened sponge otferinga sufficient and increasing resistance to the pressure of the water. The quantity of water entering the ship in this Way is so small that it may easily be removed by the ships pumps even when several holes have been made in different parts of the hull.

In comparison with other materials ordinarily used for fothering leaks, sponge has been found most suitable and of particular value owing to its properties of elasticity, absorbing power, incombustibility, and low specific weight. It will not become corrupt in a dry or wet condition, and can be readily applied.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

l. A ships wall provided with a lining of sponge, substantially as shown and described.

2. A ships Wall provided with a lining of compressed sponge, substantially as shown and described.

In testimony whereof l have signed my name to this specilcation in the presence of two subscribing witnesses.
